Breaks Lastpass Rated 3 out of 5 stars

This has the potential to be a great extension in the future...
For me a dealbreaker is the fact that it causes me to have to login to the Lastpass extension every time I open firefox. It seems to cause cookies to delete "every time I close firefox" instead of my default "when they expire". If this behaviour could be corrected then this might turn out to be a very special extension indeed.

This review is for a previous version of the add-on (2.1.1-signed). 

Whitelist Lastpass.com

I just checked out the Lastpass extension. It looks like you need to go to Lastpass.com and whitelist the site, so that the extension can use the login cookie across browser sessions.
